UNITED STATES PATENT OFFICE.

HARRY E. DE VAUGHN, OF MORGANTOWN, WEST VIRGINIA, ASSIGNOR TO WALTER A.

JONES, OF MOB/GANTOWN, WEST VIRGINIA.

GLASS-FURNACE.

Specification of Letters Patent.

Application filed October 6, 1918. Serial No. 124,091.

To all whom it may concern:

Be it known that I, HARRY E. DE VAUGHN, a citizen of the United States,residing at Morgantown. in the county of Monongalia and State of WestVirginia. have invented new and useful Improvements in Glass- Furnaces,of which the following is a specification.

This invention is an improved suspension device for use in glassfurnaces. and other glass handling apparatus generally. wherein theparts are subjected to intense heat.

()ne of the objects of the invention is to provide a simple device forsupporting rcfractory or silica walls, arches. or other construction. Afurther object is to provide a device of this character and means forprotecting the same from destruction by the intense heat to which it issubjected in operation.

The invention will be hereinafter fully set forth and particularlypointed out n he claims.

In the accompanying drawings Figure 1 is a front elevation of the skewblock of a glass furnace. with the invention applied thereto. Fig. 2 isa vertical sectional view thereof. Fig. 3 is a similar sectional viewtaken at right angles to Fig. .2, Fig. l is a bottom plan view of theskew block. Fig. 5 is a top plan view of the suppor ing device. Fig. (iis a view illustrat ing the' .vcnt ion up plied in suspending the claymantel walls of a flattening or annealing oven.

Referring to the drawings, l0 designates a skew block of the typeusually employed in supporting the cap of a glass furnace, said skewblock. in the form illustrated in I igs.1,2and4.beingprovidcd in itsbottom with a channel 11. leading in from the rear wall thereof. thewalls of said channel being in lined as indicated at 12. to accommodatethe undercut edges ol a protector block 13. Leading upwardly from thechannel It into the body of the skew block. is a recess H. whichcinnmunicates with bores l5. ding to the top of the block. LocatedWilllh: the recess 14 is a supporting device Ill. prct'prablyconstructed of metal, and provided \\'Illl 'an' internal chamber 17. andtop and bot tom threaded openings 18 and Hi respectivcly, the openings'19 bring in the bottom wall and of smaller diameter than the openings18, which are formed in the top Wall. Suspension rods 20, having theirupper end supported in any suitable manner, are attached to the threadedopenings 19, passing through the openings 18, and by reason of theengagement with the supporting member 16. and the supporting means forthe rods 20. not shown, the skew block may be suspended over the moltenglass. Surrounding the rods 20. and engaging the threaded openings 18are pipes 21, one of said pipes being connected to a. source of supply,and the other pipe to a discharge branch. whereby a cooling medium, suchas Water, may be caused to circulate around each of the rods 20 andthrough the chamber 17, thereby protectiug the metal parts from'theintense heat radiating from the molten glass, and from other sources.

In practice. the suspension rods 20, and the pipes 21 are first.attached to the supporting member 16. and then said pipes and Said rodsare passed upwardly through the bores 15. the suspension rods beingconnected with the supporting device in any suitable way.

The protector block 13 is then placed in position. by sliding the sameinto the channel 11. the undercut edges of said protector block and theinclined walls of said channels, serving to maintain the protector blockin position. so as to completely cover the supporting device 16. andthereby serve as an additional protect ion therefor.

In Fig. 3. in lieu of the protector block 13. a float 25 is employed.the same having a reduced portion 26. shaped to enter a recess 27 in thebottom of the skew block 10. In practice the tloater block 25 floatsupon the surface of the molten glass. and by reason of th lHHKYHHU t"thereof. the reduced portion 2a is held within the recess 27 of the skewblock. thereby covering the supporting member 16. and being also heldagainst relative disphu-ement.

In Fig. 6 the suspension device is shown as supporting the clay mantelWalls 30 of a flattening or annealing oven. said walls being providedwith recesses 31 to receive the supporting devices 16. the suspensiondevices being passed through the mantel walls and the cap or crown of toven. the iods 20 having their upper ends secured to a supporting beam3:3. sustained in any desired manner.

Having thus explained the nature of the invention, and described anoperative man nor of constructing and using the same, although withoutattempting to set forth all of the forms in which it may be made, or allof the forms of its use, the following is claimed 1. A suspension deviceof the character described comprising a Hat supporting device providedwith a closed chamber, suspending means rigidly secured to saidsupporting device, and means for guiding a cooling medium into and outof said chamber and in contact with said suspendii'ig means.

2. A suspension device of the character described comprising a flatsupporting de vice provided with a closed chamber, suspension rodsrigidly attached to said supporting device, and cooling devices surrounding said rods and communicating with said chamber.

3. A suspension device of the character described comprising a flatsupporting de' vice provided with a closed chamber, suspension rodsextending through said chamber and having threaded engagement with thebottom Wall thereof, and tubes surrounding said rods and having athreaded engagement with the top wall of said chamber and communicatingtherewith.

4; The combination with a body of refractory material having a recess inits underside, a supporting member located within and substantiallyfilling said recess, suspension means for said su porting membercxtending through said )ody, and means for cooling said supportingmember and its sus pension means.

5. The combination with a body of refractory material having a recess inits underside, a supporting member located within said recess,suspension means for said sup porting member, and a refractory memberfor closing said recess.

6. The combination vvith a body of refractory material having a recessin its underside, of a flat supporting member located within andsubstantially filling said recess, said supporting device being providedwith a closed chamber, suspension means rigidly secured to saidsupporting device, means for guiding a coolin medium into and out ofsaid chamber an in contact with said suspension means, and a refractorymember closing said recess and covering said sup porting member.

7. The combination with a body of. rei'rars tory material ha ing achannel in its under side, and a iecess leading upwardly from saidhannel, of a sug'iporting member lo cab-d within said recess, suspensionmeans for said supporting member leading through said body, and aprotector block located in said channel and covering said supportingmember.

8. The combination with a body of refractory material having a channelin its under side and a recess leading upwardly from said channel, of afiat supporting device 10- catcd Within and substantially filling saidrecess, said supporting device being provided with a closed chamber,suspension means rigidly secured to said supporting device, means forguiding a cooling medium into and out of said chamber and in contactwith said suspension means, and a protector block located in saidchannel and covering said supporting member.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit nesses.
